Abstract: PURPOSE: A hybrid timing recovery device is provided to be independent of the size of ghost and track a residual jitter by detecting timing error information in a timing offset acquisition mode by a Gardner method and detecting timing error information in a residual jitter tacking mode by a decision-directed method. CONSTITUTION: A re-sampling unit(201) re-samples an inputted baseband signal as double symbol clock frequencies, and interpolates the baseband signal with the double symbol clock frequencies. A determination signal generating unit(202) compares the level of the baseband symbol signal outputted from the re-sampling unit with predetermined signal levels, and outputs a determination symbol signal which has the most near level with the level of the baseband symbol signal.
